At my work, we recently bought Epilog Mini laser cutter and ShopBot Desktop CNC milling machine. The manager told us to master these machines (we write software to drive them) and said that we need to make anything, whatever strikes our fancy. He even bought stacks of 3mm and 6mm depron for me to cut!

I've been flying powered planes and gliders of all sizes for many years and I am a pretty decent builder. But I have never tried indoor flying and have a very vague idea of the modern designs--will embark on reading posts in this foum.

Would you kindly recommend a good design to build? I can cut 12"x24" parts on the laser cutter (I can probably do 24"x24" by having half of the sheet stick out of the front door) and 18"x24" on the milling machine. Cutting time is unlimited.

Yes, it can mill composites all right! I tested it on CF/endgrain balsa sandwiches I make for my "bigger" planes.

The mill has an Italian made industrial spindle (the more expensive option for ShopBot), which is very well balanced and spins up to 20,000 RPM, if I remember right. With the right bit, it can mill everything including metals.
